Good insight, thank you for sharing it. It didn't occur to me after I watched the OpenMower video. A very small nitpick: OpenMower is not FOSS as it's restrictively licensed prohibiting commercial use ( https://github.co

My fiber line (Mountain View, CA, US) is aerial and uses the same poles as electricity. Strong winds cause tree branches to break, which in turn often cut wires. So, they might, but it's less robust than underground, which results in m

Micropython is actually great on ESP32 despite having GC and unless heavy number crunching / camera stuff happening, it feels to be the a really good tool for the job.

Probably. On the other hand, Ukraine had the pool of engineers and scientists to maintain / develop it, while Kazakhstan might have not: it's a smaller, mostly rural country. For example, in 1991, Ukraine had 15 nuclear reactors (

Different markets require different tradeoffs. Flying things can tolerate higher cost, if it comes with a higher energy density, ability to charge/discharge quickly and (in some cases) higher cycle life. In this respect, sulfur-ion bat

Good question. I've taken a look at the final revision of the spec ([1]) and it seems that parallelizing a QOI decoder may be non-trivial, because of back references. More over, it's possible to come up with QOI-encoded images whi

Yes, the battery lifespan is the big issue (as pointed out in my original post). As for charging at 28 MW: might work, given that the battery is physically larger, so there's more space to dissipate heat. I agree that it's not pro

I assume that the majority of the cost would be to design and build nuclear ships. And it's still worth it, as fuel is 50%-60% of operational costs. As for drones to handle cases of ports which don't allow nuclear ships to dock: t

Yes, port cranes are much better, if they can be used. The drones are suggested as a potential alternative to handle "LA does not allow nuclear ships to dock", so that a transfer from a nuclear- to battery-powered container ship h

by krasin 5y ago
Cost on its own is rarely an issue. The thing that matters is payback time. If one container move generates $10, and the drone moves 12 containers per hour, 12 hours a day, it will only take 6 months to earn the quarter of million mentioned

State != military, though. For instance, all France nuclear power plants are operated by Électricité de France (EDF) that is substantially owned by the French Government, with around 85% shares in government hands ([1]). I don't see a

I agree that the old way of doing things won't work. How about hundreds of cargo drones capable of lifting containers to transfer them from one ship to another? Something like this: https://www.cognitiveseeds.com/395-2&

I share the same feelings. The thing is that these foreign companies won't ask the US for permission. And if it's profitable, they will (eventually) do it. Yes, such ships will likely have to stay away from the US territorial wate

You have a point. Let's wait until China deploys their fleet. Going to be a long wait (15-20 years), but it is my strong belief that they will do it. I might be proven wrong, of course.

Waymo essentially trained several NeRF models for Block-NeRF that are rendered together. It's conceivable that NVIDIA's instant-ngp could be used for that.

Still, NVIDIA's achievement (and Thomas Müller in particular) is amazing. Thomas and his collaborators achieved an almost 1000x performance improvement, by a combination of algorithmical and implementation tricks. I highly recommend tr

https://github.com/NVLabs/instant-ngp has a script that converts a video into frames and then uses COLMAP ([1]) to compute camera poses. You can then train a NeRF model within a few seconds. It all works pretty well. T
